"The Iguanid Lizards of Cuba" (Los lagartos iguánidos cubanos) published by the University Press of Florida in December of 1999 is the most complete work on Cuban iguanid lizards, important segment of our autochthonous fauna. The study of these reptiles is indispensable to be able to understand the dynamics of terrestrial ecosystems.

The work analyzed here, includes the results obtained during twenty years of research and the collection of dispersed existent documentation. The authors' effort has determined a remarkable contribution to biology, behavior and ecology of this zoological group, which stands out for its species diversity, abundance, its function of arthropod predator carried out in the ecosystem and active transmitter of trophic energy, among other characteristics. This work is trascendent because it is useful to carry out conservationist studies, to the appropriate handling of the territories that it inhabits and its repercussion in the environment protection.

This works provides an unavoidable tool to the field work and an informative and cognitive base for the preparation of reports, publications, and for the use and correct handling of protected areas and with an appropriate base for environmental decision making that cooperate to the use and rational conservation of Cuban fauna in general and of iguanids in particular. It is a novel work, and it is stressed the inclusion of chapters such as those of Genetics and Parasitology, unusual in faunistic guides, and also for approaching the problems carried out by urban development to conservation and biodiversity and the high number of species that live in Cuban limited territory.

The document has references from the Scientific Council of the Institute of Ecology and Systematics of the Agency of Environment (AMA) from the Ministry of Science, Technology and Environment (CITMA) and the Faculty of Biology of the University of Havana (UH) . It has also favorable opinions from the National Center of Protected Areas, the Italian Herpetologic Society and from prestigious herpetologists of the Universities Columbia, Cornell and Washington of United States of America; also, a "Book Review" has recently appeared in Caribbean Journal of Science magazine written by a noted specialist.
